I wouldn't reccomend training more than two days in a row. Anyway here are some signs of OTing:
If you experience any of these warning signs, immediately cut back on your training frequency.
Deep-rooted fatique from which you can't seem to recover
Digestion problems
A resting heart rate that is lower than normal
Lower blood pressure
If you experience any of these symptoms, cut back on your training intensity within your workouts.
Troubled sleep
Profuse...

As far as the standalone players go:
Better than Ipod.
iTunes is what makes the iPod great.

Immediately following a tough lifting session, your body needs two things - protein / amino acids and glycogen - and it needs them quickly. The ideal way to get these into your body is a shake...

Cheat meals are important.
If you are lifting weights, your recovery isn't just determined by time off, but by your diet. In general, more calories will mean quicker recovery, so after a hard workout sometimes a cheat meal will benefit you.
